Gary Helmling commented on HBASE-15111:
---------------------------------------
Just to note, since the VersionInfo output is no longer going through a logger,
it does changes the output text slightly, as it no longer contains the normal
log line prefixing.
Old output is:
{noformat}
[gmh-mbp ~/devel/hbase (master)]$ ./bin/hbase version

After the patch, output is:
{noformat}

{noformat}
I consider this an improvement, but don't know if we should consider this a
compatibility issue for such a basic command.

>
> Calling {{hbase version}} currently outputs the version info by writing to
> {{LOG.info}}. This means, if you change the default log level settings, you
> may get no output at all on the command line.
> Since {{VersionInfo.main()}} is being called, it should really just output
> straight to stdout.
